As far as we know, it will do what we say it will do, and it will also not do what we say it will not do. Therefore, please read the following discussion of the features which are supported at present and the features which are not supported! We hope to be able to do more, and if you have one of these cameras we hope that you will look for anticipated updates at the CVS tree of libgphoto2, found at <gphoto.sourceforge.net>. *************************************************************************** This library has been written specifically to support the iClick Pro 5X, a simple and inexpensive camera. A brief description of the camera may be found at <iclickphoto.com>. The camera has the USB Vendor:Product ID of 0x2770:0x9153, which would seem to indicate that it contains a chip from S&Q Technologies, Taiwan. The same company makes the sq905 chipset which is in many entry-level cameras; the chip in this camera is probably an sq915 chip, and it uses a different communication protocol. Probably, any other cameras with this chip inside will also work with this camera library, but we do not know that at this time. The camera has a flash, takes 640x480 pictures, and has a slot for a memory card. Without the memory card, it will hold 16 still photos, and with a memory card (maximum size is advertised as 128MB) it will clearly hold many more. A memory card has been tested with the camera and seems to work without any problems. The 640x480 photos can be blown up to a larger size by the OEM driver which comes with the camera. It is stated in the documentation that this is done by "interpolation" meaning that the actual amount of data is 640x480. The format of the data from the camera is a standard Bayer format, and this driver should download such photos. The photos look fairly sharp for 640x480; the color mapping could however be improved by postprocessing. For now, we recommend the use of GIMP or the old xview ("xv") program to do that after you download the photos. It is important to note that the construction of the hardware itself will not easily support downloading of random photos, which may present severe incompatibility with a GUI program such as gtkam, digikam, or similar. Thus, the user is advised to use the command "gphoto2 -P" to dump all photos on the camera into a directory. After this, the user can inspect at leisure the photos on the hard drive and can decide which ones to keep and which ones to delete. We repeat: We do not advise the use of a GUI frontend at this time, because we cannot guarantee that it will work. The camera also has two other modes of operation, which this driver does not support. There is a "video clip" feature which will shoot a number of frames. Apparently, these frames are then saved in some kind of JPEG format, and the size is given in the JPEG headers in the data as 320x240. This feature is at present NOT SUPPORTED. So please do not try to use it and especially do not try to mix clips with still photos on the camera. The fact that the clips are not of a fixed, given size will mess up your download. There is also a webcam feature. Gphoto2-libgphoto2 is in general not designed to support streaming video, which in general requires a kernel module. Abstractly speaking, the command "gphoto2 --capture-preview" can use the webcam mode to cause a tethered camera to snap a photo. This also we do not support at present. So if you make it work be sure to let us know. Taking the above caveats fully into consideration, we hope that you enjoy your experience with this camera.
